unnecessary-generator-set (C401)
Derived from the flake8-comprehensions linter.
Fix is always available.
What it does
Checks for unnecessary generators that can be rewritten as set
comprehensions (or with set directly).
Why is this bad?
It is unnecessary to use set around a generator expression, since
there are equivalent comprehensions for these types. Using a
comprehension is clearer and more idiomatic.
Further, if the comprehension can be removed entirely, as in the case of
set(x for x in foo), it's better to use set(foo) directly, since it's
even more direct.

Fix safety
This rule's fix is marked as unsafe, as it may occasionally drop comments when rewriting the call. In most cases, though, comments will be preserved.
